Four legs have I, a sturdy fellow
A fuzzy back that isn't yellow
But (often) green or (rarely) red
A den is where I make my bed
My keepers feed me coloured balls
With sticks they store on my den walls
Sometimes I store them in my pouch
Sometimes deep in my belly; ouch!
That's when you'll see me acting strange
Instead of balls, I'll eat your change
And that's my cue to feed again
Chalk it up to hunger, friend!

Answer

A billiard (pool) table.

They have four sturdy legs and a green, fuzzy playing surface (snooker tables are sometimes red). Privately owned tables are often kept in the den (family room), and the cues are usually stored in a wall rack. Private tables simply have pouches beneath the pockets to catch the balls; coin-operated tables store the balls inside the table. To play again, you need to insert more coins.

Note the use of "cue" and "chalk"; two essential billiard elements!Hide
